基于CORBA和UML的分布式系统开发方法

The Development Methods of Distributed System Based on CORBA and UML

UML和CORBA技术分别在面向对象分析和设计以及分布对象计算领域起着重要作用 ,它们的结合有助于将不同的开发阶段、不同的建模技术和不同的实现技术有机、无缝地集成 ,对于设计和实现高质量的分布对象系统有着重要的意义。本文主要介绍在实践中总结出的使用CORBA和UML开发异构分布式系统的方法 ,包括UML建模过程、CORBA组件构造过程、数据库集成过程三部分 ,当中着重强调了IDL的设计对系统性能的影响 ,而且引入了针对CORBA特性扩充UML建模的内容。

UML and CORBA take important role separately in Object-Oriented Analysis and Design and Distributed Computing, the combine of them is useful for integration of different phases of development, modeling methods, and implements, significant for design and implement of high-quality distributed system. This article mainly describes the methods of developing isomerous distributed system by using CORBA and UML in practice, that include UML modelling process, constructing CORBA components process and Database integration process. In addition, the influence of IDL design on system performance is empasized, the extension of UML modelling according to the attribute of CORBA is introduced.
